hey guys i need your help in a worst way.i have a 98 integra with a b17a bottom end and a b16a2 head.for some time now going up hill about half throttle my car will jerk like 2 times and my abs light will come on.well today i was messing around a little bit got into it pretty good took 1st to 7500 and hit second and the car did the same thing.i changed spark plugs thinking that was the issue cause they had seen better days and still did not fix the problem.i'm now confused to the issue i have no idea what the problem is so any info would be a huge help.

 

First thing I would do is check fuel pressure.

When was the last time fuel filter was changed? 94

 

i have a fuel pressure guage on my filter housing and it's reading fine.it did it to me today driving in 5th gear at 50mph and my speedo dropped.usually i would associate that with and alternator going bad from previous expierences,but where i work at advance auto parts i put it on our machine and did a system check and it read fine on everything.my car is ideling rich as hell right now like 10 to 10.5 according to my innovative afr guage.i am now more confused than ever on this.

 

i'll try to change my fuel filter this weekend and see if that will do any better.if it don't i'm going to start leaning toward my distributor.
